Daniel Han a7d415262a Keep the scoped download key derivable, and stop the hidden page hijacking a route
Four review findings, the first a regression from my own last commit:

- Keying scoped download jobs by a digest of the file set broke the
  download manager: it builds that key client-side (it polls and cancels
  before any response tells it a key), so it watched and cancelled a key
  no worker owned and never fired its ready callback. Keep the derivable
  "@scope" key and refuse the second request instead when a live job on
  the slot is fetching a different file set -- decided inside the
  registry claim, under the lock, so a concurrent claim cannot slip past
  it. The manager records the file set on the job as well, so a sibling
  quant's transfer is not adopted locally either.
- Both diffusion pages read the route query through a loose useSearch and
  both stay mounted once visited, so the hidden one consumed the other's
  ?model=: it navigated back to its own route and tried to load, say, an
  image checkpoint as a video model. Only the visible page consumes it.
- The staged download plan was built without the configured HF token or
  the Advanced values the load itself sends. The token matters most: the
  backend's Hub metadata lookup is best-effort, so a gated base silently
  planned no companion entry and the load pulled those multi-GB files
  inline, outside the manager. The memory/quant controls decide whether
  the base transformer/ shards are needed at all, and the route dropped
  memory_mode, cpu_offload, the prequant path and the LoRA selection
  before asking for the plan.
- The video preview kept playing after leaving the page: the keep-alive
  layout only hides it, and display:none does not pause a media element,
  so a clip the user unmuted kept its audio going over the next page.
  Pause on the active transition and do not auto-replay while hidden.

Also completes the hand-built request bodies in the hub download tests:
the scoped-files field this branch added to the route read as an
AttributeError against them, failing five tests.
